This object is the bit mask (8 bit wide) for
tos-overwrite feature. The
cwdxQosProfTosOverwriteValue is written where the
mark bits are set to 1.
Tos-overwrite allows the HE to mark egress IP packets
(from the HE) with a specific TOS value. This relieves
the subscriber unit from marking upstream packets with
a specific TOS and is most useful when a subscriber
unit is supplied by a third party vendor who may not
have the option of applying a TOS to an IP packet.
Each packet received from an SU that matches this QoS
profile will be tagged with the TOS-overwrite value
at the cwdxQosProfTosOverwriteMask and sent to the
network.
